gimmick or worth it?

gimmick unless you have done something to change the flash point of gasoline.

so basically they each have a little coil in it. I guess after coil-packs, this is the next logical step

and the supposedly faster flame front (see the vid) will screw up your ignition timing

yeah but when using high compression or high boost colder plugs are normally used so whats the point in attempting to make more powerful plugs?

"Do you want more torque to boost your towing capacity?"

WTF kind of statement is that? Torque isn't the reason why they limit towing capacity on vehicles. Its the vehicles ability to stop the load safely that dictates how much it is "legally" allowed to tow. Once I heard that above statement in their vid, I clicked the [x]. Bullshit product.

I mean, 350 hp/627 ft·lbf from a diesel V10 in a touareg can tow a 836,000 lb boeing 747... I'm sure they used oem plugs on that one... and they did just freakin fine.

I hope you mean glow plugs, not spark plugs.

^haha, i knew that. the point i was trying to make there was that 627 torque is enough to tow 836,000 lbs. I was just debunking their whole "you need more torque" claim.

2/9/2008 7:02:16 PM

and glow plugs have nothing to do with a diesel engine running.

dumbass

2/9/2008 8:06:04 PM

^ I didn't know that. I've never owned or had to take care of a diesel before. The only thing my dad has ever told me about diesels are that they have glow plugs instead of spark plugs and that you have to wait for them to warm up a second before you start the engine. Now I know. k thanx.

Your dad told you.... yet you still dont know it. What a fucking moron you are.

2/9/2008 9:18:38 PM

Goddamn, are you that fucking stupid that you can't read what I typed? He just told me those two characteristics about a diesel when we borrowed a friends truck to move some stuff. He never once mentioned how a diesel works and I never bothered/cared to look it up or ask. This was like 15 years ago. I didn't care about the automotive world then. Saying that they have glow plugs and understanding how they are implemented in a diesel setup are two different things.

Stop hating you stupid niggers.

The only thing that glow plugs do is preheat the combustion chamber when ambient atmospheric temps are too low for the engine to start quickly and effectively on its own. My truck doesn't even have 'em. Most big rigs don't either. Mine does have an intake manifold grid heater, though. But she'll still start without that in really cold weather.

Now almost all small engines, particularly the ones with indirect injection, have glow plugs.

What amazes me is that more engines don't have multiple plug systems in order to more fully propagate the flame front evenly. High swirl chambers and intake turbulence help immensely, but you'll notice that some engines, like the Hemis (which aren't even real hemi engines, btw) have dual plugs for that very reason. Some even have split timing to "shape" the flame front. Multiple plugs also help tremendously with engines that recirculate a large amount of exhaust gases to cut down on NOx emissions.

I ordered some for my Integra few weeks ago. The boot fit too tightly around the plug and the lead wouldnt make good contact with the plug terminal even after hammering the boot on with a mallet. This resulted in misfiring and a CEL. One of them got stuck in the boot, forcing me to have to extract it in pieces with vice-grips. The insulator half seems to be glued on to the base, and evidently they break fairly easily.

They have a 30-day money-back guarantee, which is why I didn't feel too bad about getting them. I shipped them back and am awaiting a refund.

Here's an article from my Dsport magazine. This is the lead-in with the basic concepts, etc:
http://www.dragsport.com/issue/2008/0308_tech.shtml

the results:

'00 Integra Type R (bone stock) with new oil, new NGK Laser Platinum plugs = 158.7hp 114.9tq
" " with Pulse plugs = 161.1hp 117.5tq
" " reinstalled with NGK plugs = 158.7hp 115.9tq
-type R's are highly-tuned in factory form already
-nonVTEC didn't gain too much; 5500rpm onwards got the gains
+2.36whp +2.54wtq (1.5%)

'04 G35
" " with factory NGK Laser plugs (56,000 miles) = 234hp
" " with Pulse plugs = 239.15hp
-gains all across the board increasing pretty linearly with rpm
-gains start to slowly taper after 5200 rpm
+5.2whp (2.2%)

Evo IX with AEM intake tubing
" " with old plugs (20,000 miles) = 276.5hp 266.1tq
" " with Pulse plugs = 282.2hp 269.2tq
-most gains from 5500 to redline
+5.7whp (2.0%)

I'd love to know how much money gets wasted on overpriced, unnecessary spark plugs every year. Every brand claims better gas mileage, more power, etc... but there is no real way isolate the spark plugs from the other variables involved enough to quantify it.

2/24/2008 12:22:12 AM

so 2% compared to old plugs?


and what are the odds that the ITR put down the same hp, to the tenth, on the two runs with platinum plugs?

I'm sticking to regular copper plugs. Seem to work best for the boost I'm running.

If they achieved measurable and consistent gains among multiple cars with the only change being the spark plugs, its fairly safe to say the plugs are doing something. Whats uncertain is if the ECUs had fully adapted, and whether that would have an effect on power, negative or positive.

I'd like to know how they got the boots to fit the plugs in the Integra. Maybe the Type-R has larger boots or something.

2/24/2008 1:49:02 AM

its fucking snake oil people, get over it. there is no 100 mpg carburetor and there is no magic bullet!

2/24/2008 2:26:57 AM

^^^^^those gains could be had just by making sure the spark plug is facing the proper direction.

2/24/2008 9:41:24 AM

^seriously. and what is the accuracy of the dyno? it would have to be <2% error, right?

2/24/2008 9:05:58 PM

^^yep, indexing makes a difference on some engines.

also, were the plugs they replaced brand new?

damn it you post the dumbest shit. please stop trashing the value of my ncsu degree. a more powerful plug IS the whole point and where the gains come from. you would probably see about the same results just switching to a hotter range in a conventional plug.

besides, no one even said anything about modified vehicles. did you even bother to read the site? they specifically address the issue and direct you to a similar product for non stock applications.

I NEED TO BUY.. NOW!!!

2/24/2008 9:47:22 PM

there is no better mousetrap.

2/24/2008 10:38:11 PM

Then there's the fact that in order to be accurate within 2% you would have to make sure the two dyno runs were performed with the same ambient air temperature and engine temperature.
